sensor linking question
Hey,
I've found some other posts/examples that seem to take a complicated approach to what I am trying to do and was hoping if someone could tell me if the following simple approach was possible: I have an emagine 3d visor and also a polhemus motion tracker. I have successfully linked the main view to both of these devices separately as follows: polhemus = viz.add('polhemus.dle); patriot = polhemus.addPatriot(); link = viz.link(patriot,viz.MainView); And also in another script: emagin = viz.add('emagin.dls'); viz.link(emagin, viz.MainView); However, what I would like to do is control the 'head view' of the world with the emagine sensors, and the movement with the Patriot sensor ideally with something similar to the following: emagin = viz.add('emagin.dls'); viz.link(emagin, viz.HeadView);#attach users 'eyes' to visor polhemus = viz.add('polhemus.dle); patriot = polhemus.addPatriot(); link = viz.link(patriot,viz.Body);#let user move independently of where they are looking I am hoping that this is just a matter of linking the correct objects which have so far eluded me to the sensors. Any pointers would be greatly appreciated. Thank you in advance |

To be clear, you want the orientation of the viewpoint to come from the emagin and the position to come from the patriot?

yes, that would be correct.

Then the simplest solution would be to use the viz.mergeLinkable command. Have a look in the docs for an explanation. Here is some simple code showing how to use it:
Code:
#Combine position of patriot and ori of emagin into one sensor tracker = viz.mergeLinkable(patriot,emagin) #Link tracker to main viewpoint headLink = viz.link(tracker,viz.MainView) |

Thanks for your help. That worked great, I had missed that function while looking through the help files.

polhemus.dle Polhemus Extension ** ERROR: Failed to connect to a Patriot/Liberty: Device not found ** ERROR: Failed to create extension sensor with polhemus.dle ** ERROR: Link failed (source linkable is invalid) emagin.dls eMagin v2.0 ** ERROR: Could not connect to eMagin device. Error: 80000017 ** ERROR: Link failed (source linkable is invalid) could you help me please? thank you very much |

Vizard is not able to connect to either the Polhemus or Emagin sensors.
Polhemus - Test with the following script: Code:
import viz viz.go() polhemus = viz.add('polhemus.dle') patriot = polhemus.addPatriot() viz.link(patriot,viz.MainView) Emagin - Try the following: Code:
import viz viz.go() emagin = viz.add('emagin.dls') viz.link(emagin,viz.MainView) |
